User interface
Ships[]
- Main article: Ship
All types of ships share certain UI features. Specifically, the fleet selection top bar always has the merge, stop, return, move, jump, patrol, and close UI buttons, though these are not always useable. All types of ship UI also have a goto, disband fleet, close fleet UI, and return for repairs button. Additionally, the ship or fleet's owner and name, its hull, armor and shield points, and its current orders are shown.
Military Fleet[]
Military Fleet UI
Military ships are used to protect an empire from threats or to expand its rule through force of arms. Military ships are organized into fleets which can be led by an 
admiral.
In addition to the general ship UI, the military fleet UI has the take point and fleet manager buttons. The fleet UI also shows the fleet's piracy suppression value, the command limit used and fleet power. Additionally, if an admiral is assigned to the fleet, their level, experience and traits can be seen here. The fleet's bombardment and fleet stances can also be set here, as can the fleet's home starbase. Finally, the military fleet UI has the reinforce, split, reorganize, and upgrade buttons. The design and other details of individual ships can be viewed by clicking the magnifying glass icon.
Ship Details[]
Ship Details UI
The ship details UI lists the ship's name, design and class, stats, and modules.
Science Ship[]
Science Ship UI
Science ships are used to survey celestial bodies such as planets in a star system as well as research anomalies or special projects. A science ship must be led by a 
scientist in order to perform any of its functions.
In addition to the general ship UI, the science ship UI shows the level, experience, and traits of its assigned scientist, and science ship specific orders.
Construction Ships[]
Construction Ship UI
Construction ships are used to build structures, including starbases and stations. Most structures can be built only in an empires owned systems.

Starbase[]
- Main article: Starbase
Starbases determine ownership of star systems and also act as the basic military defense for the system.
Research Station[]
A research station built in orbit of a planetary body will gather its physics, engineering and society research. They can only be built within owned systems, and they can not be built around colonized planets.
Mining Station[]
Mining stations are used to extract the 
minerals, 
energy, or 
strategic resources of the object they orbit. Mining stations are not needed to access the resources of colonized planets, and can only be built in owned systems.
Observation Post[]
Observation Post UI
Observation posts house teams of scientists conducting research and remotely observing primitive civilizations on the planets they orbit. The observation policy can be set from this UI.
Megastructure[]
- Main article: Megastructure
Megastructures are colossal projects which provide massive benefits to their owner.
Some megastructures are colonizable and therefore use the planet interface rather than the regular megastructure interface.
